Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foundation structure to be installed when installing an external member such as a fence or a fence. More specifically, the invention of this application relates to a foundation structure that facilitates construction and that can easily ensure the linearity of the arrangement of a plurality of standing columns.

[0002]

2. Description of the Related Art Conventionally, a block foundation has been widely known as one of the foundations to be constructed when installing external members such as a fence body and a fence. This block foundation is constructed according to the following procedure, for example. That is, <A> After digging the ground, lay stones and the like are laid, and a reinforcing bar is placed thereon. <B> Assemble the formwork and cast concrete. <C> After curing, the formwork is removed, and a concrete block is placed and fixed on a base foundation made of concrete to form an earth retaining foundation. <D> Next, the lower end of the column is inserted into the opening of the concrete block, and concrete is cast to erect the column.

[0003]

However, in the conventional block foundation structure, the steps of assembling and removing the formwork, fixing the concrete block and erecting the columns are required. It takes time and effort. Reinforcing bars are usually provided at a pitch of 800 mm, but in practice, they are often installed at a pitch larger than this, and in such a case, the strength becomes insufficient and There is a risk that the fixed concrete block will collapse from the connection with the base foundation with the erecting of the column.

[0004] For this reason, as an alternative to such a block foundation, there has been proposed a foundation structure in which a pillar is cast on a base foundation in concrete. However, in the case of the conventional pillar standing type foundation, since it is not a method of inserting the pillars into the openings of the arranged concrete blocks, it is difficult to stand a plurality of pillars linearly arranged and to stand up. There is a problem that it is difficult to vertically and linearly attach and fix the fence panel and the like due to the inclination and the non-linearity of each support.

[0005] The invention of this application has been made in view of the above circumstances, and solves the disadvantages of the conventional foundation structure, is easy to construct, and easily secures the linearity of the column arrangement. The purpose is to provide a basic structure that can be used.

[0006]

According to the invention of this application, as a solution to the above-mentioned problems, a base mesh of a flat net is provided at a base of a base, and a base support is provided at a lower end thereof. A basic structure is provided, wherein the mounting structure is erected by fitting to a base mesh, and a column is connected to an upper end of the base column.

Further, according to the invention of this application, a mesh mesh box is erected around a base post erected on a base mesh, and the base stanchion and the post are cast by concrete filled in the mesh box. It also provides the substructure that will be used.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a basic structure of an embodiment of the present invention.

[0009]

1 and 2 are a perspective view and a side sectional view, respectively, showing an embodiment of the basic structure of the present invention. For example, as shown in FIGS. 1 and 2, in the foundation structure of the present invention, a base base (10) of a foundation construction portion is provided.
A base mesh (20) made of a metal mesh is disposed horizontally and linearly on the base mesh, and a base support (30) is erected on the base mesh (20). The column (40) is connected to the upper end of the base column (30).
For example, in the example shown in FIGS. 1 and 2, the column (40) is a hollow cylinder, and the upper end of the base column (30) is fitted to a predetermined position of the cylinder, and the screw (50) or the like is used. The two are fixed by the fixing tool.

The base mesh (20) is a flat net formed by weaving linear wires or the like so as to cross at right angles. For example, a gap is provided between the base mesh (20) by its legs (21). I have. Various spacer members instead of the legs (21) may be employed. Base support (30)
Is a mounting bracket (3) having a pair of bent pieces at its lower end.
1), and when the bent piece of the mounting bracket (31) is fitted to the wire of the base mesh (20),
The base support (30) is erected on the base mesh (20). At this time, the base mesh (30) is horizontally arranged on the base (10), and the mounting brackets (31) of the plurality of base posts (30) are fitted to the linear wires of the base mesh (20). Therefore, the respective base posts (30) are linearly arranged and erected.

It is preferable that the base mesh (20) is in a state where the base (10) is fixed to the base (10) by the cement (60) as shown in FIG.
This is because the movement of the base mesh (20) is suppressed. The mounting bracket (31) is attached and fixed to the lower end of the base support (30) by bolts, screws, or the like. As long as it has, its shape and size are not particularly limited. The mounting bracket (31) is used in consideration of the thickness of the wire and the like of the base mesh (20), the size of the mesh width, and the size and weight of the base support (30) and the support (40).

Further, a connecting member (32) as shown in FIG. 1 may be provided on each base post (30) so that the distance between them is kept constant. This connecting member may be a rigid reinforcing bar or the like. FIGS. 3 (a) and 3 (b)
FIG. 6 is a side sectional view showing another embodiment of the basic structure of the present invention.

That is, in this example, after the base support (30) is erected on the base mesh (20), FIG.
As shown in (a), a mesh as a metal net having a mounting bracket (31) and an upper and lower opening with room for surrounding the support (40) is provided around the base support (30). A box (70) is arranged, a cement (60) is filled to a predetermined position in the mesh box (70), and a base support (30) is cast. Then, FIG.
As shown in (b), after the support (40) is connected to the upper end of the base support (30), the mesh box (7) is connected.
0) Fill the cement (60) to the upper edge and cast the base strut (30) and the strut (40). As a result, the column (40) is more firmly erected.

FIG. 4 is a perspective view illustrating a base mesh (20) provided at a corner in the basic structure of the present invention. By using the base mesh (20) bent at such a predetermined angle, the base support (30) is formed.
Can be turned at a predetermined angle to stand upright.
FIG. 5 is a perspective view showing a construction example of the base mesh (20). As shown in FIG. 5, a base base (10) is disposed by excavating the ground and laying a split stone (80) or the like by concrete molding or the like, and the base base (10) is attached to the base base (10). A base mesh (20) is provided. As mentioned earlier, this base mesh (20)
After erecting the base support (30), cement (6
Since the periphery is fixed by 0), the base is finally buried in the base (10) as shown in FIG. 6, and also functions as a reinforcing material for the base (10). It is to be noted that a retaining panel may be provided on the base mesh (20) as retaining means for the excavated surface. Such panel installation can be performed, for example, by attaching a panel fixing bracket to the base mesh and fitting the panel to the fixing bracket.

[0015] The invention of this application is not limited to the above examples, and it goes without saying that various embodiments are possible for the detailed configuration and the like.

[0016]

As described above in detail, according to the present invention, there is provided a foundation structure which can be easily constructed and which can easily maintain the linearity of the column arrangement. This makes it possible to vertically and linearly construct an external member such as a fence.
